We present a patient who became hemiparetic and drowsy 30 min after insertion of a carotid artery stent for severe (>80%) asymptomatic left common carotid artery stenosis. A carotid angiogram at this time showed widely patent vessels. Non-contrast head computed tomography showed a diffuse increase in signal intensity in the distribution of the left middle cerebral artery. Repeat computed tomography 8 days later showed no evidence of cerebral infarction or haemorrhage. The patient's arm remained weak for several months. A diagnosis of cerebral hyperperfusion syndrome was made. The features of this unusual cause of stroke are reviewed.
我们报告了一名患者，该患者在因严重（>80%）无症状性左颈总动脉狭窄植入颈动脉支架后30分钟出现偏瘫和嗜睡。此时的颈动脉血管造影显示血管广泛通畅。头颅非增强计算机断层扫描显示左侧大脑中动脉分布区信号强度弥漫性增加。8天后复查计算机断层扫描未发现脑梗死或出血迹象。患者的手臂无力持续了数月。诊断为脑过度灌注综合征。本文对这种不寻常的卒中病因的特点进行了综述。
